I don't have exakt numbers. We started with pcgi and had heavy problems under load. They disapeared with the fastCGI module coming wird zope 2.6 i gues.

I can not test on the Production system as there are 40000 users on the system and we have enougth Problems with Readconflictes and Session problems.
I'm not surprised you had problems with PCGI, it was known to be extremely slow. AFAIK it ran zope in single-threaded mode so concurrency was terrible. It sounds like you have concluded that, because FCGI is faster than PCGI, then FCGI must also be faster than mod_rewrite / mod_proxy. That's just not logical. p.s. If you're having session problems and read conflicts with 2.6, you should strongly consider upgrading to *at least* 2.7.3 and maybe 2.8. Heavy use of sessioning is still not perfect (see Dennis Allison's recent threads), but it is *much* better since 2.7.3. In addition, ReadConflictErrors are greatly reduced since the release of ZODB 3.3, which first shipped with Zope 2.8. -- Paul Winkler http://www.slinkp.com
